Hi !

 

I am trying to simulate dividing wall distillation column. Anyone have the idea which software work best and how it can be done?

 

or do just throwing some idea here.

 

I am collecting information first.

A Dividing-Wall Column (DWC) is usually a Petlyuk column system in which both columns are combined in one shell.

 

So you can model the DWC as a Petlyuk column system in any simulator.

 

On the left you see a Petlyuk column, consisting of a prefractionator and a main column. On the right you see the DWC equivalent:

 

 

 

If you have never heard of Petlyuk column, just google it. And also look on youtube.

Hi

 

I have read several articles on this subject, but the data needed to simulate incomplete.So I could not run the DWC.  

Would anybody share an example?or Hysys simulation?

thanks

Hello Apit,

It depends on the purpose of your simulation.
If you are not interested about DWC dynamic behaviour, then choose HYSYS because it is easier to

make the steady state model, else use Aspen Plus.

Here you have a PFD example. If you want more details then let me know.

sir, kindly provide some more details for simulation of petlyuk column is aspen plus.

Hello,

You can find attached an example of dwc in HYSYS, respectively one for Petlyuk configuration worked in Aspen Plus.

Enjoy
